it was a dick move to destroy the drone without simply talking to the operator first.
It was a dick move for them to fly the drone over private property without simply talking to the property owner first. The drone operators were the first to fail to extend a simple courtesy. I'm not at all surprised nor sympathetic that their lack of courtesy was returned in kind.
If she had a problem with operating a drone in the area, she could have told them so.
The drone operators were the instigator. They took the first action which precipitated the incident (flew the drone over her property). The onus was on them to ask/inform her first. Not for her to ask them to leave first.
C'mon people. Talk to each other. It's called being a good neighbor. If I'm going to take photos of private property, despite the law giving me the right to do it, I will still ask the property owner as a courtesy. Yes there's a chance the property owner might be a jerk and refuse. But guess what - there are about a hundred million property owners in the U.S. Just move on and find a different property which suits your needs and ask again. Just because you have the legal right doesn't mean you have to exercise that right there if you can just as easily exercise it elsewhere where it doesn't piss somebody else off. Most of the time the property owner is eager to talk, and I learn some interesting things about the property. And they learn some interesting things about photography.
